Skyhero Spyder 1000 with tall landing gear not enough thrust

Hey everyone I’m having some trouble getting my Spyder 1000 in the air. At full throttle there isn’t enough thrust to get in the air. Brought it back to the bench wiped pixhawk and installed a fresh 3.3.1 copter. Now again in test flight it flipped over aND broke some props. The throttle seemed weird. It would spin slowly until half the once I’ve half speed up very quickly. I have double and triple checks motor directions and props. And have done ESC calibrations. Any help would be appricated.
